Before You Begin
Remove all packing material from within and around the item. After unpacking, verify the
catalog number against the purchase order, and visually inspect the cable and each connector for
damage. If necessary, notify the carrier of any shipping damage immediately.
Cables are stored and shipped in a coil, and will retain this shape unless you allow the cable to
straighten itself. To straighten a cable, hang a short cable from its mid-point or lay a long cable on
the floor in a straight line. Any coiling that persists in the cable should relax within the next
24 hours. Doing this results in a cable that is easier to install.
Observe the following precautions when installing the cables in a servo system. Failure to observe
these safety notices could result in personal injury or damage to the motor and equipment.
ATTENTION: Arcing or unexpected motion can occur if the power, brake, or
feedback cables are connected or disconnected while power is applied to the drive.
Always remove power to the servo drive before connecting or disconnecting cables
at the drive or at the motor.
Failure to observe these safety procedures could result in personal injury or
damage to the motor and equipment.
ATTENTION: The maximum length of cabling between the drive and the motor
must not exceed 90 m (295.5 ft). Also, a maximum of two extension cables may be
connected from a motor to a drive.
ATTENTION: To avoid the hazard of electrical shock, ensure shielded power
cables are grounded at a minimum of one point. To prevent the build-up of
electrical energy, factory-supplied power cables use one of these grounding
techniques:
•
Bond the overall shield to the connector housing.
•
Connect an exposed section of the overall shield to ground.
•
Connect an exposed cable braid or a ground wire, if present, to the power cable
clamp, housing, or another suitable chassis ground on the drive.
Failure to observe these safety procedures could result in personal injury or
equipment damage.
